Status and Perception of Risk Management in Radiation Therapy: Survey Among Korean Medical Physicists
This study was conducted as part of an endeavor to improve the risk management system of radiation therapy departments in the Republic of Korea. An online survey on the status and perception of Korea’s medical physicists on risk management in radiation therapy was carried out. A total of 40 domestic radiation oncology departments participated. This survey is divided into three categories: (1) work environment; (2) risk management status; and (3) opinions on how to improve risk management. Based on the results of the survey, the conclusions that can be derived are (1) the majority of respondents have a high interest in the risk management of radiation therapy; (2) the lack of staffing is one cause of risk management difficulties; (3) a risk-related terminology and classification system at the national or professional association level are required; (4) each hospital should create a voluntary reporting system for the handling of incidents; (5) medical physicists should establish incident reporting, analysis and countermeasures; and (6) government should develop education and training programs. It was confirmed that the current risk management system should be changed by education in the hospital and at the national level in order to improve risk management related to radiation therapy. In addition, it was recognized that a dedicated staff and a risk management certification system and organization for patient safety in radiotherapy are needed.
Authors: Sexe R, Miedema BW Abstract Preview When in rectal cancer surgery can the anal sphincter be spared? For which patients is iliac lymphadenectomy advisable? Should radiation therapy and chemotherapy be given before surgery rather than after? Drs Sexe and Miedema address these and other questions in this discussion of recent advances and future trends in therapy for rectal cancer. PMID: 29219677 [PubMed]
ConclusionsTo the best of our knowledge, this is the first report about a gastric perforation after stereotactic body radiotherapy for lung tumors and it warns of serious complication of stereotactic body radiotherapy in not only centrally located but also peripherally located tumors like in this case.
Authors: Gonzalez VJ, Saligan LN, Fridley BL, Ortiz-Zuazaga H, Aaronson LS Abstract OBJECTIVE: To examine the trajectory of fatigue experienced by 26 Puerto Rican (PR) men over the course of External Beam Radiation Therapy (EBRT) and to assess gene expression changes from baseline to midpoint of EBRT using microarray technology. Design/Research Approach- Prospective exploratory and comparative design study. Setting- RT facility located in San Juan, PR. Sample/Participants-26 PR men with non-metastatic prostate cancer. METHODS: Participants completed 2 paper forms: demographics and the Spanish version of the 13-...
ConclusionThe use of an image-guided adaptive radiotherapy strategy reduced the incidence of high-grade skin toxicity and oral mucositis in the acute setting. Further studies are needed to better define which subset of patients may benefit the most.
We performed a meta-analysis and systematic review to compare the radiotherapy (RT) modalities for hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT).
We present a case of a 66-year-old male who presented with left testis mass. Histopathological analysis of orchiectomy specimen was consistent with adenocarcinoma of the rete testis. Subsequent retroperitoneal lymph node dissection revealed metastatic disease not detected on preoperative PET-CT. Prior reports have suggested poor response rates to both systemic chemotherapy and radiation therapy. Aggressive surgical management of the retroperitoneum should be considered even in clinically node-negative patients given the paucity of other effective treatment regimens.
Abstract A 58-year-old man was referred for selective internal radiation therapy for locally advanced unresectable hepatocellular carcinoma. Intra-arterial particle perfusion scintigraphy was performed with SPECT/CT following intra-arterial injection of 99mTc macroaggregated albumin. Angiography demonstrated a hepatic falciform artery, a feeding artery of the ligamentum teres, whereas scintigraphy demonstrated tracer uptake in the mid–anterior abdominal wall. The hepatic falciform artery was subsequently embolized and the repeat angiogram confirmed successful occlusion. Subsequent post–selective internal radi...

CONCLUSIONS Metastatic dissemination within the CNS can be observed in many patients with myxopapillary ependymoma. GTR of the primary tumor should be the primary treatment goal, and additional RT is recommended after STR. For distant metastases of myxopapillary ependymoma without clinical manifestation, close clinical and MRI follow-up represents a sufficient strategy because most of the metastases remain asymptomatic and do not show progression over time. Additional resection or irradiation as salvage therapy would be recommended if metastases become symptomatic. PMID: 29219779 [PubMed - as supplied by publisher]
The Xoft Axxent Electronic Brachytherapy System (Xoft, Inc., San Jose, CA) is a viable option for intraoperative radiation therapy (IORT) treatment of early-stage breast cancer. The low-energy (50-kVp) X-ray source simplifies shielding and increases relative biological effectiveness but increases dose distribution sensitivity to medium composition. Treatment planning systems typically assume homogenous water for brachytherapy dose calculations, including precalculated atlas plans for Xoft IORT. However, Xoft recommends saline for balloon applicator filling.
